Author: Deron Eriksson
Description: This Ant tutorial describes how to use the jar task to build a jar file.
Tutorial created using:
Windows XP || JDK 1.5.0_09 || Eclipse Web Tools Platform 1.5.1
(Continued from page 1) If I execute build-jar, I see the following result in the console:
Buildfile: C:\projects\workspace\team-cakes-utilities\build.xml
build-jar:
clean:
[delete] Deleting directory C:\projects\workspace\team-cakes-utilities\bin
[mkdir] Created dir: C:\projects\workspace\team-cakes-utilities\bin
copy-non-java-files:
compile-jar-classes:
[javac] Compiling 2 source files to C:\projects\workspace\team-cakes-utilities\bin
clean-jar:
[delete] Deleting directory C:\projects\workspace\team-cakes-utilities\build
[mkdir] Created dir: C:\projects\workspace\team-cakes-utilities\build
jar:
[jar] Building jar: C:\projects\workspace\team-cakes-utilities\build\team-cakes-utilities.jar
BUILD SUCCESSFUL
Total time: 1 second
In Eclipse's Navigator view, we can verify that our classes were indeed created in our bin directory, and the jarW file was created and placed in the build directory. 
We can also open our jar file to verify its contents. I did this and verified that it contained the expected class files. I inspected the MANIFEST.MF file and it contained the expected results.
